Highend buttons limitations

Buttons included in Highend are great, but seem to suffer from a couple of limitation, in my opinion.

1. Why are they all in capital letters even if button text is lower case? Why not let the content designer choose lower/upper case?

2. Only a specific number of colors are offered (turqoise, green-sea, sunflower, orange, emerald, nephritis, carrot, pumpkin, peter-river, belize, alizarin, pomegranate, amethyst, wisteria, wet-asphalt, midnight-blue, concrete, asbestos, darkly, second-light, hb-third-light, second-dark, third-dark, yellow). What about support for standard RGB color codes? I understand that it may need 2 codes (one for normal, one for hover/click), but still.

What do you think?
